Description

Technical Field

[0002] Shafts are essential components in mechanical engineering and are widely used in a variety of machinery and equipment, including machine tools, automobiles, household appliances, and aerospace. Shafts typically have multiple critical machining surfaces, including the outer diameter, inner bore, end face, keyway, and helical hole. Pin hole machining is a key step in shaft machining, involving the creation of one or more precise holes in the shaft for securing, positioning, or torque transmission.

[0003] Currently, the pin holes of shafts are usually machined with the help of mechanical equipment (e.g., bench drills and drilling machines). Since the cross-section of the shaft is mostly circular, the shaft needs to be fixed with a clamping device during the machining process. When machining different types of shafts (i.e., when the length or diameter of the shaft changes), the stability of the shaft during machining is generally ensured by replacing the fixing fixture or increasing the clamping force. However, replacing the fixing fixture not only affects the machining efficiency of the shaft but also increases production costs. In addition, increasing the clamping force of the clamping device can easily cause the shaft to get stuck inside the clamping device, resulting in material jamming. Summary of the Invention

[0027] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The following describes the shaft pin hole processing auxiliary equipment of the embodiment of the present application with reference to the accompanying drawings.

[0029] like Figures 1-8 As shown, the shaft pin hole processing auxiliary equipment of the embodiment of the present application may include: a shell 1, a conveying mechanism 2 and a pressing mechanism 3.

[0030] The two ends and the upper portion of the shell 1 are arranged in an open structure.

[0031] It should be noted that the two ends of the shell 1 described in this embodiment are arranged in an open structure, which is convenient for loading and unloading the shaft to be processed. The upper part of the shell 1 is arranged in an open structure, which is convenient for relevant technical personnel (for example, workers) to observe the processing process of the shaft and convenient for workers to inspect and repair the equipment.

[0032] The conveying mechanism 2 is disposed on the housing 1 , and includes two support shaft assemblies 21 , two transmission chain assemblies 22 , an adjustment assembly 23 and a plurality of limit assembly groups 24 .

[0033] The two support shaft assemblies 21 are respectively rotatably connected to the housing 1 , and the support shaft assemblies 21 are used to drive the transmission chain assembly 22 to rotate.

[0034] It should be noted that one end of a support shaft assembly 21 described in this embodiment is connected to a driving device, which is installed on the outer wall of the housing 1 and can drive the support shaft assembly 21 to rotate.

[0035] The two transmission chain assemblies 22 are respectively connected to the two support shaft assemblies 21 . The transmission chain assemblies 22 are used to drive the multiple groups of limit assemblies 24 and the shaft body to be processed to move.

[0036] The adjusting component 23 is connected to the two supporting shaft components 21, and the adjusting component 23 is rotatably connected to the shell 1. The adjusting component 23 is used to change the position of a transmission chain component 22, that is, to change the distance between the two limiting components 241. It not only makes the equipment suitable for processing various types of shafts, but also can adjust the magnitude of the force between the pressing mechanism 3 and the shaft during the processing.

[0037] Multiple groups of limiting components 24 are respectively arranged on the two transmission chain components 22. Each group of limiting components 24 includes two limiting parts 241. The limiting parts 241 are arranged in an M-shaped structure. The limiting parts 241 are used to provide accommodating space for the shaft to be processed.

[0038] It can be understood that the M-shaped arrangement of the limiting component 241 can form two line contacts on the outer wall of the shaft to be processed.

[0039] The limiting component 241 includes a base 2411 , a single-rod limiting member 2412 and a double-rod limiting member 2413 .

[0040] Among them, the base 2411 is set on the transmission chain assembly 22, one end of the single-rod limiter 2412 is connected to the base 2411, the other end of the single-rod limiter 2412 is connected to the transmission chain assembly 22, one end of the double-rod limiter 2413 is pivotally connected to the base 2411, and the other end of the double-rod limiter 2413 abuts against the transmission chain assembly 22.

[0041] It should be noted that the specific structures of the single rod limiting member 2412 and the double rod limiting member 2413 are as follows: Figure 4 As shown, the double-rod limiting member 2413 can be placed outside the single-rod limiting member 2412.

[0042] The pressing mechanism 3 is provided on the housing 1 . The pressing mechanism 3 is used to limit the position of the shaft to be processed above the shaft. The pressing mechanism 3 includes a bracket assembly 31 and a hydraulic telescopic rod 32 .

[0043] The bracket assembly 31 is connected to the housing 1 , and the hydraulic telescopic rod 32 is provided on the bracket assembly 31 . The hydraulic telescopic rod 32 is located above a limiting component 241 .

[0044] Specifically, relevant technicians (eg, workers) use the device in combination with an external drilling machine to perform pin hole processing on a batch of shafts.

[0045] First, use an external robotic arm or an external loading device to place multiple shafts to be processed in turn in multiple sets of limit assemblies 24. The driving device drives the support shaft assembly 21 to rotate, the support shaft assembly 21 drives the transmission chain assembly 22 to rotate, and the transmission chain assembly 22 drives the limit assembly 24 and the shaft to move at a uniform speed.

[0046] When the shaft moves to the bottom of the pressing mechanism 3 (this working condition can be obtained through the infrared sensor), the driving device stops running, and the hydraulic telescopic rod 32 in the pressing mechanism 3 applies a rated force (for example: 50N) to the shaft below it. Then, the external drilling machine drills the preset position on the shaft until the drilling is completed. The driving device continues to run, and when the next shaft to be processed moves to the bottom of the pressing mechanism 3, the above steps are repeated to complete the processing of the pin hole on the shaft.

[0047] It should be noted that the workbench of the external drilling machine is placed below the transmission chain assembly 22. When the drill rod contacts the shaft, the transmission chain assembly 22 will not be deformed.

[0048] After the driving device continues to run, the transmission chain assembly 22 drives the limit assembly 24 and the processed shaft to continue to move. Since one end of the double-rod limit member 2413 is pivotally connected to the base 2411, the other end of the double-rod limit member 2413 conflicts with the transmission chain assembly 22. After the limit assembly 24 is flipped over, the processed shaft can be unloaded autonomously and finally fall into the external collection frame, thereby avoiding the problem of material jamming and improving the processing efficiency of the shaft.

[0049] If it is necessary to process pin holes for different types of shafts (the length or diameter of the shafts has changed) in the future, workers can change the distance between the two transmission chain components 22 (two limiting components 241) through the adjustment component 23, adjust the position of the drill rod of the external drilling machine, repeat the above steps, and complete the processing of the pin holes of the shafts.

[0050] During the processing, the limiting component 241 close to the drilling position serves as a fulcrum, the distance from the limiting component 241 to the drilling position can be regarded as a power arm, and the distance from the limiting component 241 to the pressing mechanism 3 is regarded as a resistance arm. Based on the principle of lever, when processing pin holes of different types of shafts, by changing the fulcrum position, the power arm is reduced and the resistance arm is increased, so as to maintain the size of the force between the pressing mechanism and the shaft. This can not only ensure the stability of the shaft during processing, but also avoid the situation where the shaft is stuck due to excessive external force.

[0051] In one embodiment of the present application, Figure 2 、 Figure 6 and Figure 7 As shown, the support shaft assembly 21 includes a rod body 211 , a sleeve 212 and two guide rails 213 .

[0052] The two guide rails 213 are integrally formed on the rod body 211 , the sleeve 212 is sleeved on the outside of the rod body 211 and the guide rail 213 , one transmission chain component 22 is connected to the rod body 211 , and the other transmission chain component 22 is connected to the sleeve 212 .

[0053] In one embodiment of the present application, Figure 2 and Figure 5 As shown, the adjustment assembly 23 may include a connecting frame 231 and a first hand-screw 232 .

[0054] The two ends of the connecting frame 231 are rotatably connected to the corresponding sleeves 212 respectively.

[0055] It should be noted that bearings are provided between the two ends of the connecting frame 231 and the sleeve 212 described in this embodiment, the inner ring of the bearing is connected to the sleeve 212, and the outer ring of the bearing is connected to one end of the connecting frame 231.

[0056] The connecting frame 231 is arranged in a triangular structure. One end of the first hand-screw 232 is rotatably connected to the inner wall of the shell 1, and the other end of the first hand-screw 232 passes through the connecting frame 231. The first hand-screw 232 is threadedly connected to the connecting frame 231, and the other end of the first hand-screw 232 passes through the inner wall of the shell 1. The other end of the first hand-screw 232 is rotatably connected to the shell 1.

[0057] Specifically, when workers are processing pin holes for different types of shafts, they rotate the first hand-screw 232, which is threadedly connected to the connecting frame 231, thereby driving the connecting frame 231 to move, and the connecting frame 231 drives the sleeve 212 to move. The sleeve 212 moves on the rod body 211 along the guide bar 213, thereby changing the distance between the two limiting components 241, so that the distance between the two limiting components 241 is adapted to the length of the shaft, thereby expanding the scope of application of this equipment.

[0058] In one embodiment of the present application, Figure 7 and Figure 8 As shown, it also includes a feeding assembly 4, which includes two connecting plates 41, a material rack 42, a conveyor belt 43, a material shifting device 44, a temporary storage rack 45, multiple telescopic connecting rods 46 and multiple shifting plates 47.

[0059] Among them, one end of the two connecting plates 41 is connected to the shell 1, and the other end of the two connecting plates 41 is connected to the material rack 42. The conveyor belt 43 is installed inside the material rack 42. The material shifting device 44 is installed at the end of the material rack 42 and is located above the conveyor belt 43. The temporary storage rack 45 is arranged in a J-shaped structure at the end of the material rack 42. A plurality of telescopic connecting rods 46 are respectively arranged between the corresponding two limiting components 241, and a plurality of shifting plates 47 are respectively arranged on the corresponding telescopic connecting rods 46.

[0060] Specifically, the conveyor belt 43 continuously runs inside the material rack 42, and the conveyor belt 43 transports the shaft to be processed to the material dispensing device 44. The material dispensing device 44 can only provide one shaft to be processed to the temporary storage rack 45 at a time. In the process of the transmission chain assembly 22 driving the limit assembly 24 to move, the dial plate 47 can take out the shaft to be processed in the temporary storage rack 45. The shaft to be processed falls into the limit assembly 24 and moves with the transmission chain assembly 22, thereby realizing autonomous loading and improving the level of automation of the shaft pin hole in the processing process.

[0061] In one embodiment of the present application, Figure 3As shown, the bracket assembly 31 includes a first bracket 311 and a first transverse driving module 312 .

[0062] The first bracket 311 is connected to the housing 1 , the first transverse driving module 312 is mounted on the first bracket 311 , and the hydraulic telescopic rod 32 is mounted on a slider of the first transverse driving module 312 .

[0063] In one embodiment of the present application, Figure 5 As shown, the mobile platform 5 is further included. The mobile platform 5 includes a base plate 51 , a second transverse driving module 52 and a plurality of auxiliary rollers 53 .

[0064] Among them, the base plate 51 is installed on one side of the shell 1, the second horizontal drive module 52 is set on the base plate 51, and a plurality of connection holes 54 are opened on the slider of the second horizontal drive module 52. A plurality of auxiliary rollers 53 are respectively installed on the slider of the second horizontal drive module 52, and the auxiliary rollers 53 are rollingly connected to the base plate 51.

[0065] It should be noted that the external bench drill can be mounted on the slider of the second transverse driving module 52 .

[0066] Specifically, the transmission chain assembly 22 drives the limit assembly 24 and the shaft to be processed to move at a constant speed. When the shaft to be processed moves to the preset position, the first transverse drive module 312 and the second transverse drive module 52 operate simultaneously, thereby driving the hydraulic telescopic rod 32 and the external bench drill to move. The shaft to be processed is placed under the hydraulic telescopic rod 32 and the drill rod of the external bench drill. The hydraulic telescopic rod 32 and the external bench drill move synchronously with the shaft, and the three are relatively stationary, so that the shaft is processed. After the processing is completed, the hydraulic telescopic rod 32 and the external bench drill are reset, and the above steps are repeated to continue processing the next shaft.

[0067] It can be understood that the above embodiment can realize the assembly line processing of the shaft pin hole, further improving the automation level of the shaft pin hole processing.

[0068] In summary, the shaft pin hole processing auxiliary equipment of the embodiment of the present application, by setting an M-shaped limiting component on the transmission chain component, the adjustment component can change the distance between the two transmission chain components (two limiting components) according to production needs, so that this equipment can be used for the processing of various models of shaft pin holes.

[0069] During the processing, the limiting component close to the drilling position is used as a fulcrum, the distance from the limiting component to the drilling position is regarded as a power arm, and the distance from the limiting component to the pressing mechanism is regarded as a resistance arm. Based on the principle of lever, when processing pin holes of different types of shafts, by changing the fulcrum position and adjusting the length between the power arm and the resistance arm, the stability of the shaft during processing can be ensured, and the force between the pressing mechanism and the shaft can be maintained. In addition, the double-rod limiting part in the limiting component is movably connected to the transmission chain assembly. After the shaft is processed, it can complete autonomous unloading, thereby avoiding the problem of material jamming, and thereby improving the processing efficiency of the shaft.
